SPECIFICATION forming part of Letters Patent No. 728,725, dated May 19, 1903. Application filed February 17,1903. Serial No, 143,779. (No model.)

To all whom, it may concern:

Be it known that We, FERDINAND KAMKE, HENRY A. SCHMIDT, and CHARLES H. SOHA- BACKER, citizens of the United States, residing at Menomonie, in the county of Dunn and State of W'isconsin, have invented new and useful Improvements in Sleigh 7 Knees, of which the following is a specification.

Our invention relates to oscillating sleighknees; and the object of the same is to construct a knee which will be light, strong, and insure an easy rocking movement to the sleigh.

The novel construction employed by us in carrying out our invention is fully described and claimed in this specification, and illustrated in the accompanying drawings, forming a part thereof,-in which Figure l is a front elevation of our knee, together with bridge-bar and springs. Fig. 2 is a side elevation of our knee. Fig. 3 is a vertical section on the line 3 3, Fig. 2. Fig. 4 is a detail of one of the boxes. Fig. 5 is a detail of the other box. Fig. 6 is a detailsof the head.

Like numerals of reference designate like parts in the different views of the drawings.

The body of our knee consists of two fanshaped plates 1, extending substantially parallel and perforated at their lower end at2 to adapt them to be attached to an inclined sleigh-runner 3 by means of bolts. A flange l is formed on one of the plates and bears on the top of the runner 3 to support the knee. Laterally-offset boxes are carried by the upper ends of the plates 1 and extend transversely thereof to accommodate spindles 5, formed on a head 6, which fits between the plates. Shoulders 7 on each side of said head are located to engage oppositely-disposed semicircular flanges 8, formed on the inner sides of the plates and located to engage the shoulders 7 to limit the rocking movement of said head 6 to a small are sufficient to insure an easy rocking motion of the sleigh longitudinally of the runners 3. A box 9 is carried by the head 6 and serves to support one end of one of the horizontal bridge-bars 10. The

box 9 is set slightly inclined to the spindles and obliquely to the plates 1 in order that the bar 10 may extend horizontally notwithstanding the inward inclination of the runners 3. A cross-bar 11 is mounted transversely of the box 9 and is rounded out on the under side at ,12 and apertured longitudinally to accommodate a bolt 13 for securing the ends of bowed springs 14, one of which is attached to each of the arms of the bar 11.

Our knees are mounted in pairs, one on each runner3, and support. opposite ends of the bridge-bar 10.

We do not Wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of our invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a sleigh-knee, the combination of two plates located oppositely and adapted to be secured to a sleigh-runner, boxes formed on the upper ends of said plates and a head mounted between said plates and having spindles formed thereon which fit said boxes,

stops located to limit the rocking movement tally-extending bridge-bar, substantially as described.

2. In a sleigh-knee, the combination of a fan-shaped body adapted to be secured on its flaring end to a sleighrunner, laterally-offset boxes formed on said body with a head having oppositely extending spindles formed thereon and fitting said boxes, stops located to engage said headto limit its rocking movement to a small are, a box mounted on said head to support one end of a bridge-bar and bearing oppositely-extending arms rounded out on their under sides and longitudinally apertnred to adapt them to support the ends of the springs for supporting the bed, substantially as described.

3. In a sleigh-knee, a fan-shaped body, the flaring end of which is perforated to adapt it to be attached to a sleigh-knee, boxes mounted on said head and located in aiinement, a I our hands in presence of two subscribing wit- IO head provided with spindles fitting said boxes, nesses. stops to limit the rocking movement of said head, a box mounted on said head to support one end of the bridge-bar, and arms formed on said box to serve as an attachment for the FERDINAND KAMKE.
